When Republican party leaders decided not to hold a primary or caucus in Colorado, The Denver Post reported:

The Colorado system often favors anti-establishment candidates who draw a dedicated following among activists — as evidenced by Rick Santorum’s victory in 2012 caucus. So the party’s move may hurt GOP contenders such as Donald Trump, Ben Carson and Rand Paul, who would have received a boost if they won the state.

During a campaign rally on Monday night, GOP frontrunner Donald Trump called Colorado “a fix” because instead of holding an election, the GOP decided to do it through delegates.
